Pepperl+Fuchs 6000 Series purge pressurisation system

Click2Contact

Pepperl+Fuchs has expanded the capabilities of its 6000 Series purge and pressurisation system with a high-current output option, providing greater flexibility for hazardous-area applications that require higher electrical loads. By enabling direct switching of enclosure power within the system, the enhanced electronic processing control unit (EPCU) helps reduce the need for additional Ex-rated switching hardware, simplifying system design and lowering installation costs.

The upgraded EPCU features two enclosure contacts rated up to 12 A per contact, allowing a broader range of applications to be supported directly by the purge and pressurisation system. This is particularly beneficial for high-load equipment such as gas analyser systems, heated enclosures, and other applications where traditional solutions often require separate contactors or circuit breakers. By integrating the switching function into the control unit, the 6000 Series reduces wiring complexity, minimises panel space requirements and supports more compact enclosure designs.

The high-current option is fully integrated into the 6000 Series platform, a fully automatic Type X/Ex pxb purge and pressurisation system designed for use in Class I, Class II, Division 1 and Zone 1/Zone 21 hazardous areas. Combining controller, pneumatics, electrical I/O and user interface within a single enclosure, the system automatically energises enclosure power once safe operating conditions have been achieved. Compatible with existing 6000 Series infrastructure, including EPV-6000 vents, the high-current variants retain the platform’s established functionality and global certifications while expanding application possibilities for demanding hazardous-area environments.
